We studied the relationship between the genotype and clinical phenotype in 27 families with dominant X-linked Charcot-Marie-Tooth (CMTX1) neuropathy. Twenty-two families showed mutations in the coding region of the connexin32 (cx32) gene. The mutations include four nonsense mutations, eight missense
DNA-based mutation analysis on the connexin 32 gene was performed in 49 families with Charcot-Marie-Tooth disease (CMT) type 1 but without duplication involving the chromosomal region, 17p12-p11.2. Mutations were identified in five of the 49 families, and four of the five mutations were hitherto und
Charcot-Marie-Tooth (CMT) disease consists of genetically heterogeneous neuropathies. Molecular genetic procedures have shown that most patients with CMT type 1 (autosomal dominant, hypertrophic form) have 1.5 Mb CMTlA duplication containing peripheral myelin protein-22 (PMP-22) gene
The coding region of Cx32 was amplified by touchdown polymerase chain reaction (PCR) (Don et al., 1991). Three primer sets were used corresponding to nucleotides 54-77 (CX32-1) and 336-359 (CX32-2), i.e., part 1, 273-269 (Cx32-3) and 685-704 (Cx32-5), i.e., part 2, and 635-658 (Cx32-S1) and 919-938
